20 Claims. (01. 127-458) automatically baking, forming and shaping pastry in the form of a cone.

In accordance with the present invention,.plastic batter cakesare'formed in a continuous operation with intermittently advancingbaking irons. The batter cake are arranged for automatic stripping fromthe baking irons when the baking thereof is completed and while still ina plastic state, and then gripped by novel gripping mechanism. Thegripping mechanism is arranged to carry the plastic batter cakes awayfrom the baking irons to the cone-shaping apparatus. Upon reaching thecone-shaping apparatus, automatic actuation is effected to properlyorient the batter cake and deliver it therein in synchronism with theoperation of the cone-shaping spindle to produce the completed cones.

The general apparatus for forming and baking the batter cakes and alsoshaping them corresponds to that described in our '0'. S. Patent No.2,213,727, issued September 3, 1940.

The present invention is specifically directed to automaticallysuccessively transfer the batter cakes while. in a plastic state fromthe individual baking irons to the cone-forming apparatus in propersequence and synchronization with the remainder of the operations of themachine.

The invention provides novel arrangements for the gripper and transferapparatus, insuring a positive and fool-proof operation of the machinein order that a completely satisfactory, automatic mechanism results.

It is accordingly among the objects of our present invention to providea novel, automatic, coneforming mechanism eliminatin intermediate manualsteps between the charging of the baking irons with dough and the finalformation of the cone; to provide a novel batter cake gripper andtransfer mechanism and associated controls synchronized with theotherunits of the machine; and to coordinate the successive units of theconeforming machine to insure simplified and foolproof operation thereofin the automatic produc v tion of the cones.

These and other objects, advantages, and features of the presentinvention will appear from the subjoined, detailed description of onespecific embodiment thereof illustrated in the accompanying drawings, inWhich:

The. machine of the present invention coinprises essentially acoordinated system driven from a common motor drive for extruding apredeterminedv chargeof batter upon baking irons, feeding the bakingirons at a predetermined rate over a heater to form plastic cakes,automatically removing the cakes from the baking irons and transferingthem by gripper mechanism to the cone-forming unit, and finally removinthe completed cones. As hereinabove, stated, the form and physicalembodiment of the machine illustrated in the drawings is similar to thatdescribed in our U. S. Patent No. 2,213,727, with the addition of thenovel automatic cake gripping and transferring mechanism arranged toremove the plastic batter cakes from the baking irons and introduce themto the cone-forming device.

The latter mechanism constitutes the essential basis of the presentapplication coordinating with the prior described apparatus, renderingit fully automatic. The cake transferring apparatus eliminates themanual counterpart thereof of the prior machine, and is synchronizedwith the other operations of the machine, resulting in eflicient,uniform and rapid cone production. 7

Figs. 1, 2 and 3 are respectively end, front, and plan views of theapparatus of the present invention. The unitary control and drivemechanism for the apparatus is located in the bottom portion thereof atA. The batter feed device which stores and intermittently feedspredetermined charges of dough to the baking irons, is indicated at B.The intermittently driven bakingelements are located at C coacting witha heating arrangement not shown in the drawings but illustrated indetail in the above-mentioned patent. The batter cake transferringmechanism is illustrated at D. The cone-shaping apparatus is generallyindicated at E. i

The manufacturing machine is built between frame uprights 20, 20. Plates2| cover the ends of the apparatus as shown in Fig. l. A transverseframe member 22 is located along the top portion, as shown in Fig. 3.The control and drive mechanism for the entire machine is located nearthe bottom region at position A. A source of motive power is indicatedat 25 comprising an electric motor in the preferred embodiment. Motor 25is driven at a continuous predetermined speed, determining the speed ofthe cone production. Motor 25 drives the control apparatus properthrough belt 26 and pulleys 21,

28 arranged for speed reduction. Pulley 28 is secured to continuouslydriven shaft 33 of the control mechanism. Details of the control anddrive mechanism are further apparent in cross-sectional view, Fig. 5,taken along the line 55 of Fig. 2.

Control and drive mechanism Referring now to Fig. 5, continuously drivenshaft 30 contains worm 3| coacting with worm gear 32 which is keyed tocontrol drive shaft 33.

Casing 34 surrounds the Worm and worm gear drive 3|, 32, and containsbearings 35 and 36 for the drive shaft 33. Shaft 33 is accordinglycontinuously rotated by motor 25 at a predetermined speed-reductioneffective through pulleys 21, 23 and gearing 3|, 32.

At the right end of shaft 33 is mounted control system F arranged foractuating the cakegripper device and the cone-forming apparatus E in amanner to be hereinafter described. Control system F comprises cammember 40 rotatably mounted on drive shaft 33, integrally carryingpositive clutch element 4| coactable with clutch member 42 slidablykeyed with shaft 33 by key 43. Cam member 40 is driven by shaft 33 whenpositive clutch elements 4| and 42 are engaged by hand lever 45 (Fig.2), which controls the axial position of clutch member 42 throughsuitable linkage mechanism to be described, connected to bifurcatedmember 45 coupled with clutch element 42.

The cam system for controlling the operation of the batter cake grippingand transferring mechanism is located at G near the left end of driveshaft 33. The cam system G comprises cams 50 and 5| fastened together onopposite sides of guard disc 50' by screws 52. am contains hub 53 whichis connected to shaft 33 by key 54. Cams 5B and 5| are accordinglydriven in unison at a continuous rate by continuously driven shaft 33.Further details of the operation of cake transferring cam system G willbe described in connection with Figs. 6, 7 and 8.

Cake baking apparatus C is' intermittently driven step by step by drivesystem H. Crank 55, secured to the left end of shaft 33 in Fig. 5 iscoupled to bell-crank 51 in turn connected with sprocket gear 58 (Fig.2), which drives baking irons 60. The baking irons 60 are arranged in acontinuous chain and driven around a burner, details of which are notillustrated in the present case, but fully illustrated and described inour patent referred to above, in connection with Figs. 5 and. 9 thereof.Continuous rotation of crank effects a predetermined intermittentadvance of the individual baking irons in synchronism with the doughcharging and cake removing mechanism. Details of batter storing andfeeding apparatus B are not shown, since the operation of this elementis already well-established in the art. The operation and coordinationof the dough charging and cake baking features of the machine may befound in detail in our Patent No. 2,213,727. The cake is baked in fiatsheet form between the coacting baking irons. The cake is removed fromthe baking irons while still in a plastic state and introduced tocone-forming apparatus E. Automatic mechanism is provided in the presentcase to effect the removal and transfer of the batter cakes in theirplastic state in synchronization and coordination with the otheroperations of-the machine. The cake stripping, gripping and transferringmechanism, generally indicated at D, constitutes specifically and in combination with the other components of the machine, the basis of thepresent invention.

Cake gripper and transfer mechanism The apparatus generally indicated atD is arranged to automatically remove or strip the batter cakes baked insheet form on baking irons, to a plastic state, and suitably transferthe cakes to cone-forming apparatus E. The operations are effectedintermittently between advancements of the successive baking ironsections. Figs. 6, '7 and 8 are enlarged schematic illustrations, inperspective, of the cake gripper and transfer mechanism D in successivestages of its opera tion. The baking irons comprise upper plate 59coacting with a lower plate 60' across hinge 5|.

Baking irons 60, 60' are grilled or otherwise suitably embossed andindented at their coacting inner faces between which the dough is placedand then baked into sheet cake form. Baking irons 6|], 63' are arrangedin a chain form as indicated in Fig. 2, and are intermittently drivenacross an oven, not shown. Baking irons or plates 68, 60 travel inclosed relation after receiving the charge of dough. When plates 60, 60'reach the position illustrated in Figs. 6, 7 and 8, the dough has beenbaked into a suitable plastic cake.

As baking plates 60, 60' approach the position illustrated in thefigures, guide track section 65, containing rollers 63 at the front endof upper plate 50, causes plate '60 to open away from horizontal lowerplate '60 as the plates advance in their regular manner. Opening bakingirons 6| 6|) tothe position illustrated in Figs. 6, '7 and 8, exposesthe baked batter cake for removal by the gripping apparatus D. The guidetrack 65 is arranged to maintain upper plate 50 in the open positionshown for still another step in order to he charged with dough fromapparatus B. Dough v The baking of the dough charge between the bakingirons is arranged in a manner such that when .upper plate 60 is openedby the track and roller arrangement 63, 65, the plastic batter cakesheet 62 alwaysadheres to the upper plate 50, as illustrated in Figs. 6to 8. Adherence of the batter cake to the upper baking plate '60 isassured by making the grooves or indentations in the grilled face ofsaid plate deeper than those in the lower plate 60. A stripping finger,desirably in the form of a two-pronged fork riding in the indentationsof the grille face of the upper baking plate 60, is located in positionabove the top of cake 62 at an angle corresponding substantially to thatof the upper baking plate Bi}. Suitable linkage mechanism, controlled bycam system G, operates fork 6'6 against plate (iii to strip the topportion of batter cake 52 from it prior to the gripping of the cake.

Gripper jaws it, it of mechanism D, are arranged to grasp the strippedend p-ortion of cake 82, as shown in Fig. 8, and then be moved to theright to complete the stripping of the cake 01f plate fill and carry itto platform. H of coneforming apparatus E, prior to insertion into theapparatus, as shown in Fig. 6. Mechanism D is constructed to continuethe advance of gripper jaws Iii, Ill so thatthe gripped cake will beproperly inserted into the cone-forming apparatus when the jaws of thegripper open.

The mechanism D for stripping the batter cakes from the baking irons,gripping them and transferring them suitably into cone-forming apparatusE comprises several distinct coacting parts properly synchronized andcoordinated with the other units of the machine. Th immediatelyfollowing description relates to components of mechanism D; namely, tothe stripper'device 6B; the gripper apparatus I6; and the associatedcontrol members for insuring gripping and then suitable releasing of thecake at proper points in the cycle of operation.

Cake stripper The cake stripper comprises two-pronged fork E6 pivoted at13 at the end of lever M pivoted at I5 to bracket l5 carrying track 55.Lever M is oscillated by cam 50 which, with cam El, is secured tocontinuously rotating drive shaft 33, as described hereinabove, inconnection with Fig. 5. and forming cam system G. Link 'Il, pivoted at18, carries roller '53 coacting with the periphery of cam 56. Tensionspring 33 is arranged at the end of link E1 to continuously mechanicallybias cam follower 59 into coaction with cam 50. Link H is coupled withlever It by vertical rod 8I through clevises 82 and 83. While clevis 82is in the lowermost position, fork 513 is in its upper position, awayfrom the top of cake 62 on upper baking plate iiil. The tips of fork 66ride in the grooves or indentations of the plate 60. Fig. is across-sectional view through clevis l3 pivoting fork 66 to the end oflever "I4, corresponding to a cross-sectional view taken along the lineI5I5 at Fig. 2. A spring 84 is arranged to mechanically bias clevis I3clockwise against lever 74 and hence bias the points of fork 55 againstbaking plate I50, as shown in Figs. 6 to 8.

Once per revolution of cam 5!], in proper phase relation with theoperation of the machine, cutout cam section 58a permits cam follower I9to move upwards so that tension spring 80 will lift,

rod 8| and correspondingly move fork downward between batter cake E2 andupper plate 60, as shown in Fig. 8. The upper half of batter cake 62 isaccordingly peeled away from plate 60, and droops due to gravity actionpreparatory to its beinggripped by gripper jaws 70, ill. The successivebaking plates. are advanced one-step, once per revolution of shaft 33.The position of cam portion 59a issuch that thecake stripping action byfork 65 occurs when the-baking irons 50 for the cake are brought intothe position'illustrated in. Figs. 6 to 8.

Coke gripper jaws The cake gripper device comprises two coacting jaws10,16 pivoted on pin 85. Gripper jaw Til is relatively stationary withrespect to the grip per mechanism. Gripperjaw T0 is pivotally controlledwith respect to jaw IQ in a manner to be described hereinafter. Aprojection 86 on the outside face of jaw If! is connected with link 81through pivot 88. Link 87 is actuated by a toggle linkage mechanism tocontrol the opening and closing of jaws Ill, Ill at the proper amount inits cycle of operation.

Cam periphery 58 of cam member 40, carried on the right end of shaft 33,controls the closure of jaws it), Hi through suitable linkage mechanismdirectly activating rod 9i, as will be described. The opening of thegripper jaws ill, at the position in Fig. 7 during insertion of thebatter cake into cone-forming mechanismE is controlled by stop 92coacting with a follower 93 projecting from triangular plate 9 linkedwith a toggle control for the gripper jaws. This action will bedescribed in more detail particularly in connection with Figs. 9 and 14.

Figs. 12 and 13 are enlarged detail views of the gripper jaws, beingsectional views taken respectively along the lines I2I2 of Fig. 9, andI3I3 of Fig. 12. Left jaw 70' is relatively stationary with respect toarm 95 on which it is pivoted. Pivot shaft for the jaws is pinned to theend of arm by pin. 96. A spring 9? is arranged about rod 85 andmechanically biases jaw Ill outwardly to its normal position againstshoulder 98 of arm 95. Jaw Til remains in the illustrated position forcoaction with movable jaw 10 and I is movable about shaft 85 against theaction of spring 91 should it abut any object in its excursions.

Gripper jaw it is pivoted about rod 85 by hinge 99, being between theouter hinges of jaw ID as shown in Fig. 12. Both jaws we and iii are ofthe same size to suitably grip the batter cakes between them when movedinto relative juxtaposition as shown in Fig. 6. In Figs. 9 and 13, thejaws are apart in the maximum degree.

Gripper guiding mechanism Gripper jaws 1B, 10 are moved between bakingirons 6B in their open position shown, and coneforming apparatus E. Themovement is in proper synchronism, and is guided by track arrangementH30. Track system It!!! comprises insection I02 to a position nearcone-forming apparatus E.

Fig. 9 is an enlarged elevational view of track guiding arrangement I00.Roller I I is attached to gripper arm 95 adjacent the gripper jawregion. Roller H0 is arranged to ride in track slots I 02 to I to causethe gripper to traverse the track in the proper path upon motivation bythe actuating mechanism to be described further on. Track loop I03, I04,I05 is formed by looped extension III of L-track l0l coperating withcentrally located track plate I06 pivoted at point I I2. A spring I I3is mounted between supporting track H4 and plate I06 and arranged tomechanically bias the plate clockwise so that its extreme point I I5normally rests in the position illustrated in solid in Fig. 9. Theenlarged cross-sectional Fig. 11, taken along the line I l-I I of Fig.9, shows the track plate biasing arrangement, including spring I I3 andpivoted plate I06.

The position of track shifter plate I00, shown in Fig. 9, communicatesinclined track section I03 with horizontal track section I02, so thatwhen the gripper jaws are moved from right to left in their excursiontowards baking irons 60, the gripper jaws move upwards along track I03to the position illustrated in Fig. 8 to a place opposite the battercake to be removed. For removal of batter cake 62, motivation of thejaws continues to the left by operating mechanism to be described, untilroller H0 is moved downwards along track section I04 and around tosection I05 on its return movement.

As roller H0 passes horizontally back to the right along track sectionI05, track shifter plate Iilt is forced out of the way against thespring I I3 action, and the gripper jaws continue in their horizontalmovement into adjacent section I02. The gripper jaws "I0, I0 areaccordingly motivated from the left to the right and back again in apredetermined cycle of operation traveling towards the left along trackI02, up through track I03 to grip the batter cake, and around tracks I04and I05 after gripping the cake, and then returning along track I02towards the right for discharging the gripped batter cake intoconeformer E in a manner to be hereinafter described.

When the roller H0 reaches the upper left hand corner of the trackwaybetween the track sections I03 and I04, the gripper jaw '10 will beadjacent if not in contact with the grilled face of the upper openbaking plate 60, and will be disposed above the drooping batter cake 62,which has been preliminarily stripped by the fork 66. Further movementof the roller H0 downwardly along the track section I04 will bring thejaw 6'0 behind the drooping section of the batter cake 02 and the otherjaw I0 in front of it. The jaws l0 and 10' are then closed in the mannerto be described and the stripping of the cake from the upper plate 60completed, while the roller I I0 is travelling in the track section I05transversely of the cake adhering face of said plate. It will be notedthe stripping of the cake 62 from the upper plate 60 is effecteddownwardly and away from the plate 60 to prevent any tearing ordistortion in the shape of the baked cake.

Gripper mechanism D The opening and closing of movable gripper jaw I0against stationary gripper jaw 10 is effected by a toggle linkage actionin cooperation with control rod 9| and stationary dog or stop 92. Thisis effected by a novel arrangement coupled to movable jaw I0 comprisinglink 81 directly pivoted with jaw 10 at 88 and mechanically biasedtowards gripper arm 95 by spring I I0. Triangular plate 94 serves as athree-point linkage pivoted on arm 95 at point II! and pivoted with link81 at H8: and with another link I20 at point H9. Link I20 is pivoted toarm I2I of double arm lever or bell crank I22 at pivot I24. The secondarm I23 of bell crank I22 is pivoted to end I25 of actuating rod 9|.

Interlinked members 81, 94, 95, I20 and I2I form a'toggle arrangementforcontrolling the opening and closing movement of movable gripper jaw 79.Arm I2I is used to effect the closing action between jaws 70, I0 underthe actuation of control rod 9| by cam member 40 in a manner to bedescribed. Fig. 10 is an enlarged cross-sectional view taken along theline I0I0 of Fig. 9 at the position of guide roller H0 of the grippermechanism. Roller I I0 is shown coacting within the slotted trackportion I02 of track member WI, and isjoined with link 0"! through shaftI I0 which carries roller I I0 at its left end.

When control rod 9| is moved downwards, arm IZI is rotated clockwisecarrying link I20 and rotating plate 94 on its pivot III tocorrespondingly flip link 8'! directly connecting with jaw 10 towardsarm until plate 94 strikes stop pin 94 on arm 95, as is illustrated inFig. 6. The tension spring H6 holds link 81 in the newly displacedposition, effecting a firm closure of jaw 10 against jaw I0. The pointin the cycle of operation of the gripper mechanism D at which it isnecessary to open jaw 10 from jaw 10' prior to the release of the battercake 62 into cone-forming apparatus E is determined by roller 93,depending from triangular linkage plate 94 of the gripper togglearrangement, abutting dog I30 of stop 92 while mechanism D is movingfrom right to left. i. e., from the position illustrated in Fig. 6 tothat illustrated in Fig. '7.

When roller 93 abuts stop I30 during the movement of mechanism D fromright to left, it causes triangular plate to rotate counter-clockwiseabout its pivot II! and move link 81, by its pivot IIB, away from arm 95in a clockwise direction. This action returns link 81 from its closed ordisplaced position, illustrated in Fig. 6, to the open I or normalposition illustrated in Figs. 7 and 9. In Fig. '7, roller 93 has justabutted stop 92 to effect the opening of jaw I0 from I0. Continuedmovement of the gripper mechanism to the left further rot-atestriangular plate 94 until its depending roller 93 has moved higher thandog I30 so that continued movement of the jaws to the left is unimpeded.The gripper jaws then continue up along track section I03 towards thenext batter cake 02 in the baking iron 50, which has arrived in properposition for starting the next cycle of operation.

Fig. 14 is an enlarged detailed illustration of stop arrangement 92coacting with roller 93 of gripper mechanism D, and corresponds to ahorizontal sectional view taken along the line I4-I4 of Fig. 9. Fig. 10also shows the details of roller 93 and stop arrangement 92 in end view.Stop mechanism 92 is arranged on a horizontal plate I3I secured to trackIBI by screws I32. Dog I30 is pivoted to plate I3I at pivot I33. Aspring I34 is arranged to mechanically bias dog I30 to the solidposition against stop pin I35. When roller 93 of gripper mechanism D ismoving from right to left, as indicated by arrow I36, it abuts the headof dog I30 as illustrated in Fig. 14, to effect the opening of thegripper jaws I0, I0 in the manner described.

An important feature of the jaw opening mechanism resides in that dogI30 is arranged so that the jaws are not opened while gripper mechanismD carries the plastic batter cake from irons BI] at the left to itsextreme right excursion, and passes stop 92 on the way from left toright. The reason for this will be apparent hereinafter, and at presentit is sufficient to state that batter cake 62 is first moved beyond thereceiving slot 12 of the conical female cone forming mold member E tothe right until the cake reaches the feed table or platform II, as shownin Fig, 6, and properly inserted into receiving slot 12' in a directionfrom right to left. The pivotal arrangement of dog I38 about pivot I 33permits this action.

When roller 93 is in position 3 shown in dotted lines in Fig. 14, andmoving from left to right as arrow i3? indicates, roller 93 abuts therounded side of dog I30, forcing dog I 30 to pivot about point I33 intothe dotted position indicated at I39, The gripper mechanism D isaccordingly permitted to move from left to right and maintain gripperjaw's 1t], 19' firmly engaged. When the closed jaw mechanism, however,then returns from right to left, roller 93 abuts dog I33 to open gripperjaw 19 at the proper instant and release batter cake 62 into cone-formerapparatus E, as shown in Fig. 7.

Gripper motivating system The gripper mechanism D is arranged to bereciprocated between baking irons 59 shown at the left in Figs. 6 to 8,and the extreme right position, beyond cone-forming mechanism E. Thismotivation is cyclic in nature and is effected by cam 5! secured withcontinuously rotating drive shaft 33 in the following manner:--Referonce is made to Figs. 6-, 7 and 8 in the following description.Link Iii is pivoted at ItI and carries cam follower hi2 cooperating withthe periphery of cam 54. Rod It? is p-ivotally supported at its end Hi6on bracket I 31 extending from frame portion I 38 of the machine. Theopposite end of rectangular rod N55 is linked with bell crank I22 at theright end of the toggle mech anism of the gripper device.

Rod M5 is guided in slot I53 in the horizontal of track frame IfiI. RodH5 is arranged to be oscillated along track I56 under the actuation ofearn SE. A linkage arrangement connects an intermediate portion of rodN55 with th end of lever MG as follows: rod I5I,-l.-lever I 52 andadjustable link I53, I54. Rod ISI is joined to levers I62 and IE2through universal joints I 55 and 5%. Universal joints I55, I55 areemployed to compensate for non-linea-r movements between the ends oflevers I i-II and I52. L-lever IE2 is pivoted at I51, and in itsoscillation carries link I53, I56 in a reciproca-tory movement to inturn oscillate rod I45 along'slot I56 of track ItI.

The oscillation of rod I- iEbetWcen the extreme positions illustrated inFigs. 6 and 8 and back motivates gripper device D in itst cyclicmovement along the track sections m2 to I95, as hereinabove described,Tension spring I53 is connected to projection I59 of link section I54,ef-

fecting biasing action of cam follower Hi2 mechanism gripper jaw 10' bycontrol rod 9|, as is the introduction of the cake 62 into thecone-forming apparatus E and release of the cake. i

Adjustable link I53, I54isused to adjust the extreme points of movementof the gripper device D by rod I45. Slidable block I 60 is adjustablypositionable on rectangular rod I45, and link sections I53, I54 are alsoadjustable in total length by slots I62 and bolts ItI therein. Bysuitably adjusting the total length of link I53, I5 and the position ofblock I30 on rod I45, the xtreme movements of the gripper device D isaccurately predetermined.

Gripper jaw control arrangement Movable gripper jaw 10 is arranged to bemoved against stationary jaw .10 when the gripper mechanism D is in theposition illustrated in Fig. 8, corresponding to the time when fork 66peels the top section of batter cake 62 from open baking plate 66.Cammed periphery 95] of cam member 40, mounted on the right end of shaft33, is designed to effect closure of jaws 10, 19 at the proper instantthrough appropriate linkage mechanism action on the gripper togglearrangement as follows:

Cam follower It? coacts with cam periphery and is attached to one end oflever I66 pivoted at I61. Tension spring I58, normally secured to leverI 65, biases .cam followerIBS against cam 90. Lever IE6 is mechanicallyjoined with control rod 9| through rod I19 and lever III. Lever I1! ispivoted on extending bracket I 31 at pivot point I12. The other end I13of lever I'il is bent around so that rod SI is aligned with rod M5 tofreely move in slot 15f! of the upper track. Control rod 9| is pivotallyjoined with leverend I13 by clevis I'M. Rod I19 is joined withcorresponding ends of levers'lofi and. I1! through universal joints I15and I16. The universal joints I15, I16 are used to compensate for anynon-linear movement between the lever ends due to motivation by cam 90.7 Control rod III is accordingly reciprocated upwards or downwards inaccordance with the predetermined shape of cam surface 9E3 acting onroller I55. In Fig. Gthe radial distance of the effective portion of thecam 99 on roller I65 is a minimum, permitting tensionspring I63 to moverod I10 upwards, and thereby move .control rod 9| downward. The downwardmovement of rod 9| operates bell crank lever I22 in a clockwisedirection, effecting the movement of link I26 of the gripper togglearrangement towards the left and move gripper link 81 to thepositionillustrated in Fig. 6, which corresponds to the fully closedposition of jaws 1o, Iii. Such closure is effected a few degrees ofrotation of shaft 33 and cam 9%] beyond that. illustrated in.Fig. .8.The maximum radial cam portion I738 of cam SE! coacts with cam followerIE5, and the sudden'decrease of this radius causes rod 9i to be moveddownwards in the manner just described to effect closureof jaws 10, 10.r

Th opening of the gripper jaws 18, it is not controlled by rod 9| but bystop mechanism 92 located at the properposition along the track I fit.The gripper jaws remain locked upon the batter cake 62 from the momentit grips it oif thejbaking irons Iii), as shown in Fig. 8, until itcompletes its return excursion at the extreme right, as shown with Figs.9 and 14, batter cake 52 has been deposited on the feed table orplatform H of the cone-formin apparatus E, as illustrated in Fig. 6.

Platform or feed table II is inclined downwardly so that continuedmovement to the left of gripper 10, I causes the batter cake 62 to slideinto slot I2 of apparatus E, as shown in Fig. 7. As the grippers reachthe position illustrated in Fig. 7 over slot 12 of cone-formingapparatus E, roller 93 of the gripper mechanism abuts stop 92 effectingthe opening of jaw "I0 from jaw I0 discharging cake 02. Simultaneouswith the introduction of cake '62 into slot I2, the rotating spindle ormandrel I80, which is the cone-shaper member, shown in dotted lines, ismoved into guard I2, as shown in Figs. '7 and 8. Cone-shaper or spindleI80 contains ridges I8I which assist in gripping the batter cake to formit into th required cone shape. The jaws I0 and 70 are so operated as torelease the cake only after the rotating mandrel I80 has gripped thecake in the female mold member, s that upon the release of this cake themandrel will effect its cone-forming operation.

After the batter cake is released from gripper jaws I0, I0 andintroduced to the cone-forming mechanism E as described, the grippermechanism continues its motivation towards the left under the continuousactuation of lever I45 by cam to initiate its next cycle of movementtowards baking irons 60, as shown in Fig. 8, for gripping of the nextbatter cake and depositing it in apparatus E.

The cone-forming apparatus E comprises a conical female mold member I2,mounted on an axis substantially parallel to the hinge axis of thebaking irons in stationary discharge position thereof, and is formedwith a pair of opposed flanges Ila and 'II spaced to define a slot 12constituting an entry opening for the cake into the interior of the moldmember I2. The flange Ila spaced nearest to the baking irons forms atable over which the cake slides in its movement towards the right, andis elevated above the flange II. The flange 'II inclines slightlydownwardly towards the left, and serves as a feeding table for the cakeas it is moved by the jaws I0 and I0 towards the left in its returnmovement. The section I Ib of the cone-former between the mold section12 and the flange Ha is inclined downwardly towards the left to serve asa guide surface for directing the forward edge of the cake 62 into theinterior of the mold I2 as this cake is fed through the slot I2.

The mandrel or shaper I90 has a series of spaced teeth thereon extendingalong its face for gripping the cone blank or cake in the process of theformation of the cone. The actuation of this mandrel I80'in synchronismwith the cake transferring mechanism will be now described.

Cone forming mechanism Mechanism E for forming the cone from plasticcakes 62 deposited therein is actuated by grooved cam I90 of cam member40. Front view Fig. 2 shows the completed sugar cones I9I in trough I92.This figure also shows in elevation the introduction of batter cake 02into slot I2 of the cone-forming apparatus E. Spindle or mandrel I80 iswithin cone guard I2 upon receiving plastic batter cake 62. Spindle I80is continuously ro tating to form a cone I9I from cake 62 in the usualmanner.

Spindle I80 is mounted at the end of rod I95 which is rotated at acontinuous rate through sprocket chain I96 connected to shaft I91 and inturn to continuously rotating shaft 30 through second sprocket chain I98and appropriate sprocket wheels I99 and 200, as shown in Figs. 1 and 4.Shaft I9! is rotatably supported in bearings 20I, 202 secured to uprightframe section 20. Shaft I95 is rotatably supported in bearing 203 and isslidable therein to permit the insertion and withdrawal of spindle Iinto guard I2. Sprocket chain I drives shaft I through sprocket wheel205, shown in elevation in Figs. 2 and 3. Spindle shaft I95 has asuitable keyway 206, as shown in Fig. 3, slidably coacting with acorresponding key in sprocket wheel 205 (not shown). Thus, shaft I95 canbe reciprocated with respect to sprocket wheel 205 and be continuouslyrotated thereby.

Cone-shaper or spindle I80 is accordingly arranged to be inserted inguard I2 at the time batter cake B2 is delivered thereto by jaws 10,corresponding to the position illustrated in Figs. 2 and 7, and removedto permit the completed cone I9I to drop to trough I92. The illustratedmechanism for accomplishing this end is similar to that described in ouraforementioned Patent No. 2,213,727. Upright lever 2I0 is rotatablycoupled to cone rod I95 by coupling piece 2II between collar 2I2attached to shaft I95 and compression spring 2I3. The connection betweenlever 2 I0 and shaft I95 is such as to permit coupling member 2 to moveshaft I95 and pivot with respect to lever 2I0 despite the arcuate pathwhich lever 2I0 is constrained to move in due to its pivoting at 2I4.

A cam follower 2I5 is attached to lever 2I0 near the bottom thereof andis arranged to move within grooved cam I90 of cam member 40, as shown inFig. 2. Supporting links 2I6 and 2H are pivoted to lever 2I0 at theposition of follower 2 I5 to suitably support the lever in itsoscillatory movement. Cam I90 causes lever 2I0 to oscillate cone-formerI80 into and out of the cone-forming mold or guard 12 in synchronizationwith the other coordinating operations of the machine hereinabovedescribed. A stop 220 projects from the frame and is arranged to abutthe end of the completed cone as spindle I80 moves past it, releasingthe cone into trough I92. A pusher 22I projects from the top of lever2I0 and rides in a slot in trough I92 to push the dropped cone I9I intoalignment with the other cones, as illustrated in Fig. 2.

A lever 45 is arranged for manual actuation, to stop the reciprocatingmovement of coneshaper I80 by stopping the rotation of cam member 40.Lever 45 is pivoted to frame upright 20 at pivot 222, as shown in Fig. 2and operates link 225, which is coupled to positive clutch member 42throughfork 46, shown in Fig. 5. As previously described, clutch member42 is slidably keyed to drive shaft 33 on key 43, and when engaged toclutch member 4| effects the continuous rotation of cam member 40.

The engagement of clutch members II and 42 causes the continuousoperation of the apparatus in the manner previously described. However,when lever 45 is operated to disengage the clutch 4| and 42 to theposition shown in Fig. 5, cam member 40 is not rotated, and cone-shaperspindle I80 is not oscillated. The control rod 9| which operates theclosure of gripper jaw I0 is also rendered ineffective during thisinterval, since cam surface 90, which cyclicly actuates control rod 9|,is also stopped since it is a part of cam member 40, v

Summary of operations In accordance with the present inventiomthecone-forming machine is rendered completely automatic in that it doesnot require any manual passed over a suitable burner, not shown in thepresent case but clearly indicated in the drawings of our aforementionedPatent No. 2,213,727.

After suitable baking, the batter cake is somewhat cooled and in aplastic state when the top baking plate 50 is automatically opened bythe.

raised track guide 65 to the position illustrated in the figures. theupper baking iron which is tilted at a predetermined angle when opened.A stripper fork E6 is at that time actuated while the baking unit isstationary and in discharge position to strip the top portion of thebattercake 62 away from opened iron fill. The stripped end of battercake 62 is then engaged between jaws iii, '59 of the gripper mechanismwhich has arrived at that position, as shown in Fig. 8. Peripheral camiii! then effects a downward actuation of control rod 9| to causemovable jaw '70 to close against stationary jaw ll of the gripper andgrip the batter cake 62 therebetween.

The gripper mechanism D is then motivated towards the left by the samecam i w hich con trols rod M5, permitting the batter cake 82, tov

be introducedinto slot 12 of the cone guard '52, as shown in Fig. 7. Atthat instant roller 93 of. the gripper mechanismabuts dog i323 of stop92 to immediately open the gripper jaws 79, ill and effect the releaseof the batter cake into the cone-v forming apparatus E, as shown. inFigs, 2 and '7. This release is effected at the instant the mandrel I83has gripped the cake.

The motivation of the gripper mechanism D' continues, towards the leftup inclined track slot liltto the position of Fig. 8 opposite the nextbat- The batter cake 52 adheres to ter cake tobe gripped,.thuscompleting the cycle of operation for the gripper mechanism. It is to beunderstood that in the interim the baking irons have been advanced byone position, due to their intermittent motivation through sprocket gear58,,showhin Fig. 2.

The spindle its is rotated curin the period,

of its engagement with the batter cake 62 introduced into the slot. 73to instantly form it to the required cone shape The rotation of the spindie I85) stops upon formation of the cone and is thereupon Withdrawnfrom guard l2 by grooved cam I96 and lever 2W described in connectionwith Figs. 2 and 5, whereupon the completed cone is kicked off spindlelBii and dropped into positionin trough I92.
